Pump Options

SF Modification

Special fluid application. Incorporates dual seals with bleed port to atmosphere. This modification prevents contamination of air motor by fluid being pumped.

B Modification

For tank top installation. Inlet check valve is installed in bottom of hydraulic cylinder. For other applications, check valves can be reversed.

CF Modification

To insure 100% contamination-free hydraulic fluid operation, air motor is isolated from hydraulic assembly. Also, this model can pump fluids up to 400°F.

DS Model

DS Modification

The De-stroke model uses a modified air piston to shorten the stroke, which helps prevent internal pump damage due to rapid loss of pressure. Commonly used for burst testing applications.

LPS Model

LPS Modification

For low pressure starts using air pressure of only 5 psi, increases the output pressure range of the pump

NL Model

NL Modification

Pump air motor components are lubricated with a non-melting silicone grease to provide long term lubrication. Eliminates the need to fit an air lubricator in the pump air drive line.

Materials of Construction

Air Motor

Mainly anodized aluminum with wound composite air cylinder, carbon steel zinc plated tie bolts and Nitrile seals.

Hydraulic Section

Standard pumps have 303 stainless steel cylinders, pistons and check valves, Internal check valve parts are 300 series stainless steel except for the balls which are 440C stainless steel. Nitrile seals are standard (other compounds are available). All hydraulic pistons are hard chrome plated. Other material options are available, contact us for more information.
